CNC 171 ACCESS MANWAY
The CNC 171 access Manways are secured access manholes designed to seal the tank up to 2.5
psig, with access obtained via the locking seal unlike the emergency manways which will relieve
at a given pressure, this is ideal if you you require a locked / sealed manway with access for
maintenance and cleaning
The access manway is secured by a transverse beam which is attached to the centre of the cover. This ensures even distribution of the holding down force to form a gas tight fitting to 2.5psig.
The access manways are manufactured by MTP in our UK manufacturing plant to exacting quality standards and backed by over 40 years experience as manufacturers. Standard sizes range from 18″ (450mm) to 24″ (600mm), non standard sizes available upon request.
